How to use monitor as television

My 13" tube tv just went out. It currently sits directly next to my 19" flat panel. I'm not ready to purchase a new tv just yet. Need to get a laptop first. Is there a way I can run my cable into the computer and then be able to watch on my monitor?

It also comes with some Arc-Soft "Total Media" software that previous buyers seem very happy with.
Anyway it's worth a look. The external type tuners are kind of neat since you can just pack up and move it easily to the next computer. This unit has a standard 75 ohm "F" connector input (hooks up right to an antenna) and not some proprietary thing-a-ma-bob.

I have no personal experience with K-world's products, so someone might want to ring in and share their's.

NO ANALOG TV with this unit digital only, you've been told. It does support High-Def though!
